main/unl0kr/0001-libinput-release-keyboard-keys-in-lvgl-directly-afte.patch

+Patch https://github.com/calebccff/lv_drivers/pull/5, to be integrated
+properly into lv_drivers.git / unl0kr upstream. Add it as separate patch
+for now as this is a workaround for the very annoying "can't type fast"
+bug and it's v23.12 release day.

+Subject: [PATCH] libinput: release keyboard keys in lvgl directly after
+ pressing
+
+This enables fast typing on hardware keyboards as keys are no longer forgotten.
